Form 9B — Kitchen Hood Fire Suppression System Fitness Certificate

What Form 9B is and why it exists?

Form 9B is one of the uniform forms of the Fire and Rescue Authority used in the business licensing process, and its full name is: "Fitness certificate for a kitchen hood fire suppression system under SI 5356 Part 1." In practice it is a signed certificate attesting that the fire suppression system installed inside the commercial kitchen hood was inspected and found fit and operating as required. The form is included in the business licensing file of any entity that cooks on a commercial scale — a restaurant, café, catering, hotel, hospital, educational institution and more.

The reason the form exists is simple and critical: kitchen hoods are one of the highest fire-risk points in a business. Grease that accumulates inside the hood, in the filters and in the ventilation ducts is excellent combustion fuel. When a flame breaks out from a pan or an oven, the grease can ignite within seconds, and the fire spreads quickly into the ducts. A suppression system embedded in the hood is the first line of defense — it extinguishes the fire at its source even before the firefighting crew arrives.

What exactly does the form certify?

The form relates to a fixed fire suppression system embedded directly inside the hood: discharge heads (spray guns) distributed above the cooking equipment, a suppressant tank, an automatic activation mechanism based on temperature sensors or fusible links, and a manual activation arm for emergencies.

When the temperature crosses a certain threshold or the fusible link melts, the system activates automatically: the suppressant is discharged into the fire zone, and at the same time the system is supposed to shut off the gas and electricity supply to the cooking equipment so as not to "feed" the fire anew. The practical meaning: even if a grease fire breaks out at a moment when no one is standing at the range, the system responds on its own and blocks the path to disaster.

SI 5356 Part 1 in plain language — and why the distinction between Part 1 and Part 2 matters

This is the nuance that most business owners miss. Israeli Standard 5356 is divided into two parts according to the type of suppressant:

• SI 5356 Part 1 — dry chemical fire suppression (dry chemical powder, equivalent to the American standard NFPA 17). This is the part to which Form 9B relates.
• SI 5356 Part 2 — wet chemical fire suppression (Wet Chemical, equivalent to NFPA 17A). This part has a separate uniform form.

Therefore it is important to know which system is installed at your site: if the system is of the wet chemical type — the correct certificate is not Form 9B but the form corresponding to Part 2. Submitting the wrong form is a common mistake that delays licensing files. In any case, the standard defines the requirements for design, installation, inspection and maintenance, including:

• Full coverage of all cooking sources (gas ranges, electric griddles, fryers, grills) within the system's spray range.
• Automatic shutoff of gas and electricity when the system activates.
• Matching the suppressant and the location of the discharge heads to the type of hazard and the equipment.
• A manual activation arm that is accessible and clearly marked.
• Periodic maintenance and pressure tests of the tanks, with documentation.

The overarching principle: anything that can burn within the hood area must be covered. Therefore any change in equipment layout requires re-examining whether the system still covers all the points.

Who must submit the form and when?

Any business operating a commercial kitchen with a hood and an embedded dry-chemical suppression system will require Form 9B in the following situations:

• Opening a new business: as part of the business licensing file submitted to the authority. Without a valid certificate — it is very difficult to obtain a license.
• License renewal or a condition demand: in businesses whose license is conditional on fire-service requirements, presenting an updated certificate may be required.
• After a material change: a change in equipment layout, expanding the kitchen or replacing cooking equipment requires a re-inspection and an updated certificate.
• After the system has actually been activated: if the system was discharged (even accidentally), a refill and inspection must be carried out and a new certificate obtained before returning to operation.
• At a fire inspector's demand: in a routine inspection, the inspector may demand the presentation of a valid certificate.

Who is authorized to complete and sign the certificate?

This is one of the topics that cause the most confusion. Signing Form 9B cannot come from just anyone familiar with hoods, and certainly not from the business owner.

The party who actually signs is usually a licensed technician on behalf of the system manufacturer or its authorized distributor. The form itself requires stating the details of the system's manufacturer/distributor and of whoever performs the maintenance, so the identity and competence of the signatory are a substantive part of the certificate. As a rule, whoever installs and maintains the system in practice is also the one authorized to inspect it and sign.

It is important to emphasize: the business owner or kitchen manager cannot sign the form themselves, even if they carried out a visual inspection. Nor is a technician who handles hood cleaning but is not licensed for the specific system type qualified to sign. Always ask the technician to present their certification for the system installed at your site. If you are unsure which requirements apply to your business, consult a fire-safety advisor or contact the licensing division of the Fire and Rescue Authority directly.

Certificate validity and inspection frequency

The frequency of inspection and maintenance derives from the provisions of the standard and the demand of the fire authority, not from an arbitrary "rule of thumb." The accepted practice in the field, which fire inspectors expect, is a periodic maintenance inspection at least once a year. In cooking- and grease-intensive businesses (large restaurants, high-volume catering) it is customary to shorten the interval and perform maintenance more frequently.

Separately, professional cleaning of the hood, filters and ventilation ducts must be carried out at a frequency suited to the volume of activity. Cleaning is not part of the 9B certificate, but it is essential: grease accumulation impairs suppression effectiveness and increases the fire risk. The certificate itself, Form 9B, is issued by the licensed party after inspecting the system — not by the cleaning company.

What the fire inspector actually checks?

In an inspection, the inspector is not satisfied with a quick glance at the form. Here is what is actually checked:

• Is there a signed and valid Form 9B in the business file, signed by a licensed party?
• Do the details on the form match what is installed on site — the system type (dry chemical), the number of discharge heads, the type of suppressant and the equipment coverage?
• Have there been changes to the cooking equipment since the last inspection that were not updated?
• Is the gas and electricity shutoff activated automatically when the system operates?
• Is the manual activation arm accessible, clear and clearly marked?
• Is the tank pressure correct and the system not "expired" in terms of maintenance?

Common mistakes — the nuances worth knowing

• Submitting the wrong form: using Form 9B when the business has a wet chemical system installed (Part 2). Confirm in advance which part of the standard your system belongs to.
• Replacing cooking equipment without updating the inspection: a new oven or a grill that was moved may fall outside the coverage range. An old certificate will not protect you — neither legally nor for insurance.
• A technician not licensed for the system type: certification for one brand or type is not valid for another. Check that the signatory is licensed for the system installed at your site.
• A certificate without a gas/electricity shutoff test: a classic oversight — checking the discharge heads but not verifying that the energy shutoff works. This is a mandatory requirement.
• The form exists only in digital form: an inspector asks to see the certificate immediately at the business. It is important to also have an accessible copy in the file.
• Confusing cleaning with inspection: cleaning the hood alone is not enough to issue Form 9B — these are two separate services, even if the same company sometimes performs both.

Practical tips for the business owner and building manager

• Keep an orderly paperwork file: Form 9B, the hood-cleaning certificate, the supplier invoice and the system details — all in one place.
• Arrange in advance that the inspection will explicitly include a test of the gas and electricity shutoffs, and ask for this to be noted on the form.
• Set a reminder in advance — preferably months before expiry or license renewal — so as not to be caught by surprise.
• Whenever adding cooking equipment, consult the inspection company before installation, not after.
• Make sure all kitchen staff know where the manual activation arm is and how to activate it in an emergency.
